Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added pragma to allow non case sensitive symbols Added "nosymbolcase" and "symbolnocase" pragmas to cause symbols defined while the pragma is in effect to be treated as case insensitive. Also documented the new pragma.
